To design a Proximal Tibial Model using the tibial component, the cancellous and the cortical bones; and assembling these three parts together.
Additionally, to construct a new bone and tibia assembly and run Finite Element Analysis (FEA) on the model using Pro Mechanica to determine the Maximum Principal Stress and the von- Mises Stress exerted by the model.
1. Effective kinematics restoration
2. Long term performance
3. Long term fixation
4. Installation with minimal damage to collateral structures
Tibial tray and stem constructed using the 10-32 thread
Cortical and Cancellous bone designs to fit the tibia
A/P and M/L curvatures would match the normal knee
Excellent range of tibia sizing options: SIZE 1 used (reference: www.endotec.com)
FEA analysis on the proximal tibial model completed
Stress analysis and Results obtained
Results show that the von-Mises stress and the Maximum Principal Stress are highest on the top surface of the tibia and the bottom curvature. This is understandable since the load is applied on the tibial surface. Also, the cutout on the bone shows a high stress due to the force applied on the tibia
